A neurophysiological study into the foundations of tonal harmony.
(Neuroreport, 2009-02-18)Our findings provide magnetoencephalographic evidence that the mismatch-negativity response to two-note chords (dyads) is modulated by a combination of abstract cognitive differences and lower-level differences in the auditory ... -
Amygdala, Hippocampus, and Ventral Medial Prefrontal Cortex Volumes Differ in Maltreated Youth with and without Chronic Posttraumatic Stress Disorder.
(Neuropsychopharmacology, 2016-02)Posttraumatic stress disorder (PTSD) is considered a disorder of recovery where individuals fail to learn and retain extinction of the traumatic fear response. In maltreated youth, PTSD is common, chronic, and associated ... -
Changes in Brain Resting-state Functional Connectivity Associated with Peripheral Nerve Block: A Pilot Study.
(Anesthesiology, 2016-08)BACKGROUND: Limited information exists on the effects of temporary functional deafferentation (TFD) on brain activity after peripheral nerve block (PNB) in healthy humans. Increasingly, resting-state functional connectivity ... -
Co-activation of the amygdala, hippocampus and inferior frontal gyrus during autobiographical memory retrieval.
(Neuropsychologia, 2005)Functional MRI was used to investigate the role of medial temporal lobe and inferior frontal lobe regions in autobiographical recall. Prior to scanning, participants generated cue words for 50 autobiographical memories and ... -
Cross-hemispheric collaboration and segregation associated with task difficulty as revealed by structural and functional connectivity.
(J Neurosci, 2015-05-27)Although it is known that brain regions in one hemisphere may interact very closely with their corresponding contralateral regions (collaboration) or operate relatively independent of them (segregation), the specific brain ... -
Emotion-attention network interactions during a visual oddball task.
(Brain Res Cogn Brain Res, 2004-06)Emotional and attentional functions are known to be distributed along ventral and dorsal networks in the brain, respectively. However, the interactions between these systems remain to be specified. The present study used ... -
Entorhinal cortex volume in older adults: reliability and validity considerations for three published measurement protocols.
(J Int Neuropsychol Soc, 2010-09)Measuring the entorhinal cortex (ERC) is challenging due to lateral border discrimination from the perirhinal cortex. From a sample of 39 nondemented older adults who completed volumetric image scans and verbal memory indices, ... -
Imagery and retrieval of auditory and visual information: neural correlates of successful and unsuccessful performance.
(Neuropsychologia, 2011-06)Remembering past events - or episodic retrieval - consists of several components. There is evidence that mental imagery plays an important role in retrieval and that the brain regions supporting imagery overlap with those ... -
Lateralized activation of Cluster N in the brains of migratory songbirds.
(Eur J Neurosci, 2007-02)Cluster N is a cluster of forebrain regions found in night-migratory songbirds that shows high activation of activity-dependent gene expression during night-time vision. We have suggested that Cluster N may function as a ... -
Neural mechanisms of context effects on face recognition: automatic binding and context shift decrements.
(J Cogn Neurosci, 2010-11)Although people do not normally try to remember associations between faces and physical contexts, these associations are established automatically, as indicated by the difficulty of recognizing familiar faces in different ... -
Rapid modulation of sensory processing induced by stimulus conflict.
(J Cogn Neurosci, 2011-09)Humans are constantly confronted with environmental stimuli that conflict with task goals and can interfere with successful behavior. Prevailing theories propose the existence of cognitive control mechanisms that can suppress ... -
Role of the midbrain dopaminergic system in modulation of vocal brain activation by social context.
(Eur J Neurosci, 2007-06)In a well-studied model of social behaviour, male zebra finches sing directed song to court females and undirected song, used possibly for practice or advertisement. Although the two song types are similar, the level of ... -
Sensory-motor transformations for speech occur bilaterally.
(Nature, 2014-03-06)Historically, the study of speech processing has emphasized a strong link between auditory perceptual input and motor production output. A kind of 'parity' is essential, as both perception- and production-based representations ... -
The architecture of cross-hemispheric communication in the aging brain: linking behavior to functional and structural connectivity.
(Cereb Cortex, 2012-01)Contralateral recruitment remains a controversial phenomenon in both the clinical and normative populations. To investigate the neural correlates of this phenomenon, we explored the tendency for older adults to recruit prefrontal ... -
The neural basis of involuntary episodic memories.
(J Cogn Neurosci, 2014-10)Voluntary episodic memories require an intentional memory search, whereas involuntary episodic memories come to mind spontaneously without conscious effort. Cognitive neuroscience has largely focused on voluntary memory, ... -
The short and long of it: neural correlates of temporal-order memory for autobiographical events.
(J Cogn Neurosci, 2008-07)Previous functional neuroimaging studies of temporal-order memory have investigated memory for laboratory stimuli that are causally unrelated and poor in sensory detail. In contrast, the present functional magnetic resonance ... -
What the brain stem tells the frontal cortex. II. Role of the SC-MD-FEF pathway in corollary discharge.
(J Neurophysiol, 2004-03)One way we keep track of our movements is by monitoring corollary discharges or internal copies of movement commands. This study tested a hypothesis that the pathway from superior colliculus (SC) to mediodorsal thalamus ... -
When strangers pass: processing of mutual and averted social gaze in the superior temporal sulcus.
(Psychol Sci, 2004-09)Using functional magnetic resonance imaging (fMRI), we investigated brain activity evoked by mutual and averted gaze in a compelling and commonly experienced social encounter. Through virtual-reality goggles, subjects viewed ...
